DESCRIPTION
FLO ET Industrial N5100 Series Pumps are designed for
light general commercial and industrial applications.
These pumps are constructed from a selection of
materials for handling a broad range of chemicals*.
NOTE: Not to be used with any Fluids with a flash point
below 100˚F (38˚C).
*For Chemic l Comp tib lity of di phr gm m teri l

INSTALLATION & OPERATION INFORMATION FOR MODELS N5100XXX
NOTE: For m ximum running life do not exceed
80 PSI (5.5 b r) G s Inlet Pressure

MOUNTING
The FLO ET N5100 Series self-priming pump should be
mounted in a dry and adequately ventilated area. This
pump can be mounted several feet from the tank, above
or below the fluid level. For most applications, no more
than 4 feet above the fluid level is recommended. This
is not a submersible pump.
Secure Pump to desired fixture by screws through the
mountng bracket. Ports must be facing down.
HOSE CONNECTIONS
Product In - Use 3/8” (10 mm), reinforced, flexible,
non-collapsible hose or equivalent. Avoid sharp bends
that could restrict flow or cause hose to collapse under
vacuum.
Product Out - Use reinforced 3/8” (10 mm) I.D. hose
for discharge tube.
Gas In - Make sure gas regulator is set at zero. Use
reinforced 1/4” (6 mm) hose. connect “Gas In” to gas
supply fitting on regulator. If pumps are installed in an
enclosed area, it is recommended to connect a hose
to the gas discharge port (exhaust) and vent gas to
atmosphere. (Requires ‘small’ exhaust port)
PLUMBING
Use a flexible hose to avoid excess stress on pump
ports. DO NOT crimp or kink hose. All hose should be
the same size as the pump port fittings.
All fittings must be compatible with fluid being pumped.
It is recommended to use plastic fittings only.
The use of check valves in the plumbing system could
interfere with the priming ability of the pump. If
unavoidable, check valves in the pumping system must
have a cracking pressure of 2 PSI or less.
Use a minimum 40 mesh strainer or filter in the tank or
pump inlet line to keep large foreign particles out of the
system.
OPERATION
At start-up, regulate gas pressure to desired setting. For
most installations 20 PSI (1.4 bar) inlet will be adequate,
although DO NOT go below 20 PSI (1.4 bar). Pump will
operate according to air supply. Flow and pressure can
be adjusted by increasing or decreasing gas pressure to
accommodate varying product viscosities, length of
lines or other installation conditions. Review flow curves
located on page 1 for further assistance. High viscosity
fluids and hose length will limit priming distance.
IF PUMP I T0 BE U ED IN HIGH FLOW, LOW
PRE URE APPLICATION , ADJU T GA PRE URE
TO 20 P I (1.4 BAR) ABOVE DI CHARGE PRE URE.
CONTINUOU OPERATION AT 120°F (49°C) WILL
REDUCE PUMP LIFE.
AIR MUST BE DRY AND OIL FREE.
Compressors must have dryers and/or a water
separator in the air distribution system. Pumps that fail
due to water in the air chamber will not be covered
under the limited warranty.
GENERAL SAFET INFORMATION
Protect yourself and others by observing all safety
information. Follow all safety codes and the
Occupational Safety and Health Act (OSHA).
DO NOT PUMP GA OLINE OR
FLAMMABLE LIQUID OR U E WHERE
FLAMMABLE VAPOR ARE PRE ENT.
If used with C02or N2be sure the area is
well ventilated.
CAUTION:
Do not clean or service FLO ET pumps, hoses or valves
while the system is pressurized. Plastic CO2air inlet
ports do not have a check valve. Prior to cleaning or
servicing, purge the pump by carefully tilting the pump
so ports are facing up and remove suction line from
source. Turn air off and disconnect air inlet line. (Brass
air inlet ports have a check valve.)
PREVENTIVE MAINTENANCE TIPS
Tips to help prolong your pump’s life.
• If pumping liquid other than water. pump should be
flushed with water (if applicable) after every use.
• Before freezing conditions occur, pump must be liquid free.
• If mounting pump in an outdoor environment. shield
pump from environmental extremes (i.e. sunlight.
water from washdown spray, rain, etc.).
• When using an air compressor, use an inline air dryer
placed before the pump to limit water build-up.

DISASSEMBL PROCEDURE
Remove all gas lines and suction/discharge fittings from
pump. This is accomplished by using a flatbladed
screwdriver. Slide the retaining clips away from the gas
“in,” suction and discharge fittings. Then pull the fitting
away from pump body.
Using a 5/16” (8 mm) socket, remove the 4 nuts and
washers and pull out the body bolts.
The end caps, mounting brackets will separate from the
pump. Grab a piston in each hand and twist each side
counterclockwise. Remove the piston, diaphragm,
piston seal and retaining washer from one side of the
drive shaft.
Place drive shaft into a vise with wood block jaws and
rotate counterclockwise to release old diaphragm.
Install new diaphragm and hand tighten.
CAUTION: Do not damage the surface of the drive shaft.
Using a razor blade or sharp knife, cut label on the front
of the pump along the seam in center of body.
With pump label facing you, slowly pull body apart.
Disconnect exhaust hose from muffler and pull spool
valve stem from body. Discard body gasket and old
spool valve subassembly.
To assemble new spool valve subassembly, insert
internal exhaust hose spring into exhaust hose. Connect
hose to spool valve. Mount torsion springs into spool
valve straight side first. Push torsion springs through
spool valve to bent/hook end. Lubricate spool valve
stem and insert stem into left side of pump body making
sure torsion springs are positioned in retaining niches.
Carefully push spool valve into pump until torsion
springs snap inward and lock into place. Reconnect
exhaust hose to muffler fitting.
CAUTION: If exhaust hose is not reconnected to
muffler fitting, pump will not operate.
Position new body gasket and the two o-rings and press
pump body together. Reinsert gas “in’’ fitting, discharge
and suction fitting into pump and slide retainer clips over
fittings until they snap into place. This will help hold the
pump together during assembly.
Lubricate and carefully reinsert the drive shaft through
the pump body. Install new diaphragm and piston
assembly onto drive shaft and hand tighten. Note
positioning and direction each part is facing.
Position end caps onto pump body. Insert body bolts
through pump body. Install washer, split washer and hex
nut on each bolt.
Note: Remember to insert mounting bracket into niches
on the body before installing end caps and bolts.
With a 5/16” (8 mm) nut driver, alternately tighten each
body bolt maintaining even pressure around pump body.
Using a 5/16” (8 mm) torque wrench tighten body bolts
to 20 inch lbs.
